the manual Muscle Examination for rotator cuff strength an electromyographic investigation
American Journal of Sports Medicine, 1996Co-Authors: Bryan T Kelly, Warren R Kadrmas, Kevin P SpeerAbstract:The electromyographic activity of eight Muscles of the rotator cuff and shoulder girdle (supraspinatus, infraspinatus, subscapularis, pectoralis, latissimus dorsi, and the anterior, middle, and posterior deltoid) was measured from the nondominant shoulders of 11 subjects during a series of 29 isometric contractions. The contractions simulated different positions used for strength testing of the rotator cuff and involved elevation, external rotation, and internal rotation at three degrees of initial humeral rotation (-45 degrees of internal rotation, 0 degree, +45 degrees of external rotation) and scapular elevation (0 degree, 45 degrees, 90 degrees). Isolation of the supraspinatus Muscle was best achieved with the test position of elevation at 90 degrees of scapular elevation and +45 degrees (external rotation) of humeral rotation. Isolation of the infraspinatus Muscle was best achieved with external rotation at 0 degree of scapular elevation and -45 degrees (internal rotation) of humeral rotation. Isolation of the subscapularis Muscle was best achieved with the Gerber push-off test. This study used four criteria for identifying the optimal manual Muscle test for each rotator cuff Muscle: 1) maximal activation of the cuff Muscle, 2) minimal contribution from involved shoulder synergists, 3) minimal provocation of pain, and 4) good test-retest reliability. Based on the results of this study and known painful arcs of motion, an objective identification of the optimal tests for the manual Muscle testing of the cuff was elucidated.

eyelid ptosis from sympathetic nerve dysfunction mistaken as myopathy a simple test to identify this condition
Journal of Neurology Neurosurgery and Psychiatry, 2007Co-Authors: Giuliano Tomelleri, Gaetano Vattemi, Massimiliano Filosto, Paola ToninAbstract:Acquired isolated unilateral or bilateral blepharoptosis has many aetiologies. When the pupils are normal, a myasthenic syndrome or myopathy has to be ruled out. If the tests for myasthenia gravis are negative, the next step is to perform a Muscle biopsy to establish a diagnosis. Muscle Examination may show a mitochondrial disorder, non-specific abnormalities or be quite normal. We identified three patients, who had previously undergone various investigations, including a Muscle biopsy, whose lid ptosis disappeared using eye drops containing naphazoline nitrate, a sympathomimetic drug, thus suggesting partial Horner's syndrome. We emphasise the usefulness of this simple and cheap test before performing more traumatic and expensive investigations.

Evaluation of ELISA, neck Muscle, tongue and eyelid Examinations for the diagnosis of swine cysticercosis in a highly endemic area of north India
Experimental parasitology, 2013Co-Authors: Aloukick K. Singh, Satyendra K. Singh, Kashi Nath Prasad, Amrita Singh, Anamika Bajpai, Mohibur Rahman, Ravi Prakash Rai, Rakesh Gupta, Mukesh Tripathi, Nuzhat HusainAbstract:Swine cysticercosis is very common in the developing countries where pigs are raised. Undercooked measly pork consumption leads to taeniasis; Taenia carriers act as source of human and swine cysticercosis and neurocysticercosis. Diagnosis of swine cysticercosis is important to break the cycle of disease transmission. The present study compared the neck Muscle, tongue and eye Examinations, and serum ELISA with different preparations (crude lysate, cyst fluid, scolex and cyst wall antigens) of Taenia solium cyst for the diagnosis of swine cysticercosis. Total of 24 pigs initially identified by neck Muscle, tongue and eyelid Examinations were purchased from local slaughter house and subjected to MRI for confirmation of cysticercosis. Sera from 20 MRI confirmed infected pigs and 50 disease free controls were subjected to ELISA with T. solium cyst antigens. Neck Muscle Examination was 100% sensitive and 75% specific for the diagnosis of swine cysticercosis, whereas tongue and eye Examinations were 70% and 25% sensitive, respectively. ELISA with crude lysate had 85% sensitivity and 98% specificity. ELISA with cyst fluid, scolex and cyst wall antigens showed 70%, 65%, and 45% sensitivity, respectively. The present study showed that neck Muscle Examination was highly sensitive but less specific, while ELISA with crude antigens had reasonable sensitivity and high specificity for diagnosis of swine cysticercosis. ELISA with crude lysate can be used as a screening tool for swine infection.
